Phoenix Ravens demonstrate self defense
Tech. Sgt. Jeffrey Cadogan (in red man suit), Raven instructor with the U.S. Air Force Expeditionary Center's 421st Combat Training Squadron, and Tech. Sgt. Daniel Koenigsmann, also a Raven instructor, hold a Raven demonstration March 19, 2008, in the Center on Fort Dix, N.J. In this stage of the demonstration, Sergeant Koenigsmann is using verbal judo to calm the "aggressor." Phoenix Raven is a specialized course for security personnel teaching subjects such as internal and external aircraft security, self defense and weapons handling. (U.S. Air Force Photo/Tech. Sgt.
